Introduction ABOUT THIS MANUAL Snohomish County's water resources — its streams, lakes, wetlands, groundwater, and Puget Sound — play an important role in the quality of life we enjoy. They provide us with recreation and drinking water, support tourism and salmon and are used by industry. These waters, however, are vulnerable to pollution from a wide variety of human activities. This manual applies to those residential properties and activities in unincorporated Snohomish County that have the potential to contribute pollutants to stormwater runoff or directly to receiving waters. Stormwater runoff may seep into the ground, drain to a storm drain or a drainage ditch, or flow over the ground. Regardless of the way runoff leaves your site, it ends up in a stream river, lake, wetland, groundwater or Puget Sound. Contaminated stormwater can negatively affect every water body it enters. Therefore, this manual provides detailed information on what you can do to reduce the contamination of surface water, groundwater,and stormwater from your property. Many of our water pollution problems are due in large part to pollutants washed off the land by storms. The quality of "stormwater" from residential properties is an increasing concern nationwide. Many people believe that stormwater is "clean" and does not harm water quality. This perception is understandable since the amount of pollution from any one place is not usually significant by itself. But when all these small amounts are combined,they can cause significant pollution problems. The federal Clean Water Act mandates that cities and counties control the quality of stormwater runoff. One way to achieve this is to implement pollution prevention measures on individual properties. By following the"Best Management Practices"described in this manual you can do your part to protect our streams,groundwater,and Puget Sound. BEST MANAGEMENT PRACTICES ... WHAT ARE THEY? Best Management Practices(BMPs)are a set of activities designed to reduce stormwater pollution. BMPs are separated into two broad categories:source control and treatment. Source Control BMPs Source control BMPs prevent contaminants from entering stormwater runoff by controlling them at the source. Some source control BMPs are operational, such as checking regularly for leaks and drips from equipment and vehicles, covering materials that have potential to add pollutants to surface water if rainwater comes in contact with the materials, cleaning up pet waste, and minimizing use of pesticides, fertilizers, and insecticides. Other source control BMPs require use of a structure to prevent rainwater 1
